Can you do a tut on how to make a non food item heal you or give you a potion effect or shoot lightning or blow **** up? kinda like a magic wand?

I'm trying to make a titanium block out of 9 titanium rods and when I go to craft I get this error.

If you need the Block Source here it is.


and if you need anything else let me know. Everything else works perfectly.

If you need the Block Source here it is.

package net.minecraft.src;
import java.util.Random;
public class BlockTitaniumSolid extends Block
{
public BlockTitaniumSolid(int i, int j)
{
  super(i, j, Material.rock);
}
public int quantityDropped(Random random)
{
  return 1;
}
public int idDropped(int i, Random random, int j)
{
  return mod_TorgsMod.BlockTitaniumSolid.blockID;
}
}

and if you need anything else let me know. Everything else works perfectly.

You didn't register BlockTitaniumSolid.

What about my question Techguy?

I didn't really do anything yet, except do the 'Getting Set-Up' part.
Up until it said 'All of the decompiled Minecraft files will be in mcp61/src/net/minecraft/src.', everything was fine.
But when I checked /src/, no folders. Completely empty. Now I'm confused about this, and I'm checking other (video) tutorials, and all of them have a folder in it (with the same thing inside). I didn't start coding yet, and followed all your instructions. What happened?

Did you put your bin folder containing the minecraft.jar with modloader already? And then press decompile?

No, just realized that (3 seconds after you told me).
Now it works

Hello, I have a question. I have a mob working and appearing. It attacks me and jumps and everything. I have a few questions though:
1. How to make some of the body parts to move? I know it's somewhere in model****.java, but I don't know what exactly.
2. How to make them like wolves who are neutral then becomes hostile when provoked?
3. Final question, how to make the mob act like the wolves in packs, when once a wolf is hurt, all of them will attack.

Thanks!

BTW, thanks MICHAELNESS for the help.

1. The setRotationAngles method in ModelBiped or ModelQuadruped.
2. Look at the wolf's entity class
3. Look at the wolf's entity class.

Techguy, how do I get a mob so spawn a structure? I've tried but I can't seem to get it to work :/

I'd also like to know how to get new mobs fight off other hostiles.

I'm not sure what you mean. Do you mean that it generates a stucture at its location?

Hey, about the neutral unless provoked thing, you said in your tutorial that only EntityMob can have damage, but EntityMob always attack the player. How to make them neutral unless provoked? Or there any other way?

Quote from StrangeOne101

Yeah, sort of. Every so often (rarely, actually), I want the entity to look like it's building, then a structure is spawned relative to it's current location.

Hmm, I'm not sure sorry. Try asking in Mod Development.

When modding, if you're not sure how to do something, always think to yourself, "Is this done in the game already?". Then, if it is, you just go and find the class for what it is you want to do. For example, you want a neutral mob. Pig zombies are also neutral. EntityPigZombie.java will show you how to do what you want to do. MCP also includes what all the methods are used for now, so the comments in the code should help you.

Thanks I Feel so stupid right now, I even looked at that line of code like 80 thousand times.

Whoa! Thank you very much! Pigzombie was the last thing in my mind because I rarely even go to the nether. I'll take that tip! Thanks!

Quote from Koadmaster

If you are making your own mob then you can do it without editing base classes. But if you just want to make the default mobs not burn you can go to EntityZombie (or EntitySkeliton or whatever) and make if so that it extends something like EntityNoSun then just make a new file named EntityNoSun, copy the code from EntityMob, and take out the chunk of code that tells it not to spawn in the daytime, and the chunk that tells it to burn. Or you could just take all that code out of EntityMob.

Is there any way you can explain a bit more, like which code I'd have to remove... Also, why wouldn't creepers burn if that is the problem? Or maybe TechGuy can help a bit? BTW, I am using an already existing mob

i feel the same :/

Quote from ChillyConCarnage

Is there a way that I can compress all my custom blocks into one file like the Block.java? Also items? All the Block are Ores and the items Ingots.

I don't see why you would need to, the many Block or Item files will in no way lag your game, but having multiple mod_ files will. So why do you need to?

I have a question once im done coding where do i put the files and texture I made???? Also nice tutorials!!!
